Mineral carbonation involves the capture and storage of carbon dioxide in carbonate minerals. Mineral carbonation presents opportunities for the recycling of steel slags and other alkaline residues that are currently landfilled. The Carbstone process was initially developed to transform non-hydraulic steel slags [stainless steel (SS) slag and basic oxygen furnace (BOF) slags] in high-quality co...
An investigation was carried out in an aluminium recovery works after the simultaneous occurrence of haemolytic anaemia in two workers in the slag disposal plant. The first worker was admitted to hospital suffering from nausea, backache, and haematuria. Jaundice developed on the next day. His urine contained protein, urobilin, haemoglobin, and methaemoglobin but no red cells. During the course ...
Most of the iron in the world is produced using a blast furnace process, which has iron ore (iron oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the top of the blast furnace. Coke is the primary fuel and reduc...
In situ refractories are defined as brick or unshaped products, which react internally or with furnace atmospheres and/or slag components so as to be enhanced in their performance. Examples of such products are discussed with emphasis on those that are currently employed and are being developed for the melting of iron and steel. Some strategies for the development of future in situ products are...
Limestone filler is a raw material that is already used in several applications like paints, bricks, bituminous mixtures...etc. Moreover, and particularly in Belgium, classical additions for concrete like fly ashes and granulated blast furnace slags are becoming rare; there is a need for new additions that could have a positive effect on the properties of the fresh and hardened cementitous comp...
Slag-containing pastes and concretes were analysed by element-specific synchrotron-based techniques to determine the speciation of iron on crushed materials through spatially resolved micro-spectroscopic studies. The investigated cement samples hydrated either in laboratory, or exposed river sea water. Metallic iron, along with minor proportions sulphide magnetite was detected laboratory sample...
Abstract A tapping process model of the steel from basic oxygen furnace (BOF) addressing reactions in ladle is proposed. In model, effective equilibrium reaction zone (EERZ) method applied to describe steel/slag interfacial reaction. The bulk (steel/inclusion/lining wear) and slag (liquid slag/slag additions/lining are considered. thermodynamic library—ChemApp used perform calculation. includes...
